Ryan, who's requested that his last name be withheld, tells BuzzFeed that the shirts and Instagram account are "simply a light-hearted way to engage people in politics."

"Politics is a very serious conversation, but that doesn't mean you have to be serious in showing your support," Ryan says. "Finding new ways to catch voters' attention is going to be vital in the 2016 cycle, especially for millennials."

"It is rare to find a politician that has been in favor of same-sex marriage since the start of his or her career. Even Barack Obama was publicly against it until 2012. The bottom line (no pun intended) is that Hillary supports it now. And as long as she's fighting for LGBT rights, I'll be happy!"

Ryan says that this speaks to the importance of LGBT rights in today's political landscape.

"After seeing how the country reacted to the religious freedom laws in Indiana, it's clear that LGBT rights are a serious topic in today's political landscape."

"Hillary knows that LGBT issues will be a huge asset during her campaign, because support of same-sex marriage and non-discrimination laws is a fundamental human rights stance to many young voters. The more that LGBT issues are a part of the conversation, the better Hillary will do with her millennial audience."
